Working group V-OBS coordinates all issues related to the operation of
geomagnetic observatories around the world. The WG sets quality
standards for measurements and for data processing, and supports
observatories in need of modern instrumentation or those in danger of
closure. It cooperates with INTERMAGNET and is responsible for the organisation
of a Workshop On Geomagnetic Observatory Instruments, Data
Acquisition and Processing every two years. The working group maintains
a list of observatories operating worldwide.

This working group defines formats for data exchange and sets quality
standards for indices of magnetic activity. The latest format for
observatory data dissemination is the IAGA2002 format. Numerous indices of magnetic activity exist and new ones are
often developed for different scientific purposes. WG V-DAT cooperates
with ISGI and is
responsible for assessing and recommending new indices for official
adoption by IAGA.

The main task of WG V-MOD is to coordinate international scientific
efforts to model and understand the internal geomagnetic field.
In particular, the WG assesses and adopts a new International Geomagnetic
Reference Field (IGRF)
every five years, from candidate models submitted by different research
groups. A special task group of WG V-MOD members was in charge of
coordinating the development of the first World Digital Magnetic
Anomaly Map, published in 2007.

Data and model issues

A task force to investigate the possibilities of referencing geomagnetic data products by DOI (Digital Object Identifiers) and to report in two years time was established by working group V-DAT, led by Monika Korte [September 30, 2013]

A new task force to oversee the revision of the WDMAM was established by working group V-MOD, led by chair Jerome Dyment [September 30, 2013]

A task force to oversee the revision of the IGRF and to report in two years time was established by working group V-MOD, led by Chris Finlay [September 30, 2013]

The final report on the activities of the 'Task Force for the Endorsement of PC as an IAGA index' during the 2011-2013 period, with documents considered (1, 2, 3, 4, 5) during the Merida IAGA Assembly. The definition of the polar cap (PC) index for north and south poles, and the report and recommendation of the task force, was accepted by a vote of the Division and by the IAGA executive committee in Merida. The index is therefore now adopted as an official IAGA index [September 30, 2013]

The ISO Standard 16695 Geomagnetic Reference Models is now at the Final Draft International Standard (FDIS) stage. Updates on project status
